The afterglow of the Big Bang, the cosmic microwave background (CMB), is one of our best tools to study the beginning of the Universe and how it works. Find out how we look at this “baby picture” to infer how our Universe works, what it has taught us, and what else we hope to learn. Discover how astrophysicists are building extremely sensitive tools to precisely measure the CMB, and join us on a virtual tour to find out about how scientists live and work at one of the most remote observatories on Earth: the Amundsen-Scott South Pole Station.
Cyndia Yu is a PhD student in physics at Stanford, where she works on building new tools to study the astroparticle universe. She is involved in CMB experiments around the world, including the BICEP/Keck experiment series, the South Pole Observatory, the Simon's Observatory, and CMB-S4, where she has done everything from designing and testing new detector systems to thinking about new ways to analyze CMB data to learn about the Universe. As a National Science Foundation Graduate Research Fellow and Stanford Enhancing Diversity in Graduate Education Fellow, outside of the lab she is committed to building a more equitable and just physics community and communicating the joys of science to the broader public.
